Some genetic tests are already available, although most of them are used in developed countries. Recently, tests have been developed to detect mutation for a handful of more complex conditions such as breast, ovarian, and colon cancers.
However, gene tests may not detect every mutation associated with a particular condition because many are as yet undiscovered, and the ones they do detect may present different risks to different people and populations.
The absence of privacy and anti-discrimination legal protections in most countries can lead to discrimination in employment or insurance or other use of personal genetic information. This raises questions such as whether genetic privacy is different from medical privacy.
These include the use of genetic information in reproductive decision-making and the possibility of genetically altering reproductive cells that may be passed on to future generations. Thus, any error in technology or judgment may have far-reaching consequences though the same can also happen through natural reproduction.
Ethical issues like designed babies and human cloning have also given rise to controversies between and among scientists and bioethicists, especially in the light of past abuses witheugenics see reductio ad hitlerum.
These center on the capabilities and limitations of doctors and other health-service providers, people identified with genetic conditions, and the general public in dealing with genetic information.
Effects on social institutions. Genetic tests reveal information about individuals and their families. Thus, test results can affect the dynamics within social institutions, particularly the family. Gene therapy 9 Gene therapy using an Adenovirus vector. A new gene is inserted into an adenovirus vector, which is used to introduce the modified DNA into a human cell.
If the treatment is successful, the new gene will make a functional protein. Gene therapy may be used for treating, or even curing, genetic and acquired diseases like cancer and AIDS by using normal genes to supplement or replace defective genes or to bolster a normal function such as immunity.
It can be used to target somatic i. In somatic gene therapy, the genome of the recipient is changed, but this change is not passed along to the next generation. In contrast, in germline gene therapy, the egg and sperm cells of the parents are changed for the purpose of passing on the changes to their offspring.
There are basically two ways of implementing a gene therapy treatment: They are then exposed to a virus carrying the desired gene. The virus enters the cells, and the desired gene becomes part of the DNA of the cells. The cells are allowed to grow in the laboratory before being returned to the patient by injection into a vein.
As of Junemore than clinical gene-therapy trials involving about 3, patients have been identified worldwide. These trials focus on various types of cancer, although other multigenic diseases are being studied as well.
Gene therapy faces many obstacles before it can become a practical approach for treating disease.
Genes are inserted into the body using gene carriers called vectors. The most common vectors now are viruses, which have evolved a way of encapsulating and delivering their genes to human cells in a pathogenic manner.
Scientists manipulate the genome of the virus by removing the diseasecausing genes and inserting the therapeutic genes. However, while viruses are effective, they can introduce 10 problems like toxicity, immune and inflammatory responses, and gene control and targeting issues.
In addition, in order for gene therapy to provide permanent therapeutic effects, the introduced gene needs to be integrated within the host cell's genome.

Some viral vectors effect this in a random fashion, which can introduce other problems such as disruption of an endogenous host gene. Since gene therapy is relatively new and at an experimental stage, it is an expensive treatment to undertake.
This explains why current studies are focused on illnesses commonly found in developed countries, where more people can afford to pay for treatment. It may take decades before developing countries can take advantage of this technology.
Limited knowledge of the functions of genes. Scientists currently know the functions of only a few genes. Hence, gene therapy can address only some genes that cause a particular disease. Worse, it is not known exactly whether genes have more than one function, which creates uncertainty as to whether replacing such genes is indeed desirable.
Multigene disorders and effect of environment. Most genetic disorders involve more than one gene. Moreover, most diseases involve the interaction of several genes and the environment. For example, many people with cancer not only inherit the disease gene for the disorder, but may have also failed to inherit specific tumor suppressor genes.
Diet, exercise, smoking and other environmental factors may have also contributed to their disease. The DOE and its predecessor agencies were assigned by the U.Biotechnology Insulin crystals.
